Daly River residents are holding a community meeting to discuss evacuation plans as the river continues to rise.

The Bureau of Meteorology says ex-tropical Cyclone Carlos is moving very slowly across the region and dumped hundreds of millimetres of rain overnight.

Andy McTaggart in Daly River says the river is just above 13.6 metres, and is expected to rise to 14 metres by 4pm.

He says the community will discuss where to move the sick and elderly if the river gets to 15 metres.

"We've just spoken to the clinic and at the community meeting they will bring a list of people who are ill that need to be evacuated to somewhere or Darwin Hospital or aged care facilities somewhere else," he said.

Gary Higgins from the Mango Farm Tourist Park says residents in low-lying areas have been advised that their homes could be inundated.

He says the only way out may be by helicopter.

Northern Territory Police have been on flood watch at Adelaide River and at the Darwin River Dam area.

At least five Darwin River houses were inundated by floodwaters yesterday.

Police will check for anyone stranded in their home today.

They say the Stuart Highway has opened at Adelaide River where water levels are dropping.

But Acting Commander Tony Fuller says there is still a danger of crocodiles moving close to houses in areas affected by floodwaters.

"There's some fairly large crocodiles in that area," he said.

"Members of the community are keeping an eye on the waterways and we urge anyone down there to keep away from the water, not only for the crocodiles but the potential for drownings."

Tony Blums from the Jumping Crocodile Cruises on the Adelaide River says water is under his house and neighbours have also been flooded.

"We're built up nicely to a metre and a half, but we're under water," he said.

"The boats are sticking up in the air and the house is already under water."

Wadeye police held a community meeting to ensure residents are prepared for the possibility of wild weather over the weekend.

Police have door-knocked the community and say people have been moved from surrounding outstations so they can be closer to emergency services.
